  • 0

I’m having trouble setting up the HTTP Post android app code to upload a file, string, or byte array to CherryPy. Can someone point me in the right direction?

I get HTTPError: (404, ‘Missing parameters: myFile’).
CherryPy code:

       html += """            <h2>Upload a file</h2>
        <form action="upload" method="post" enctype="multipart/form-data">
        filename: <input type="file" name="myFile" /><br />
        <input type="submit" />
        </form></body></html>"""

def upload(self, myFile):
    out = """<html>
    <body>
        myFile length: %s<br />
        myFile filename: %s<br />
        myFile mime-type: %s
    </body>
    </html>"""

    size = 0
    f = open(myFile.filename, 'w')
    while True:
        data = myFile.file.read(8192)
        if not data:
            break
        size += len(data)
        f.write(data)

    return out % (size, myFile.filename, myFile.content_type)
upload.exposed = True

Android app code:

              String writeOut = "1,1234,4567,8910";
              byte[] byteArray = writeOut.getBytes();

              File tmpFile = new File("/sdcard/Download/tst.txt");

              HttpParams params = new BasicHttpParams(); 
              params.setParameter("myFile", "myfile1");
              HttpConnectionParams.setConnectionTimeout(params, 15000); 
              HttpConnectionParams.setSoTimeout(params, 5 * 60 * 1000); 
              HttpClient client = new DefaultHttpClient(params); 
              HttpPost  post = new HttpPost("http://192.168.1.123:8080/upload"); 
              HttpEntity requestEntity = new FileEntity(tmpFile, "multipart/form-data;boundary=--");
              post.setEntity(requestEntity); 
              HttpResponse response = (HttpResponse) client.execute(post); 
              int statusCode = response.getStatusLine().getStatusCode();
              HttpEntity entity = response.getEntity();
              String page = EntityUtils.toString(entity);
              Log.d(HTTPTAG, "reply: " + page);
              Log.d(HTTPTAG, "statuscode: " + statusCode);
